Filed Oct. 17, 1958, Ser. No. 767,929 2 Claims. (Cl. 2052.1)

, This invention relates to a window construction and more particularly to a laterally sliding window which can be selectively slid from the window opening into a dummy blind or shutter.

An object of the present invention is to provide a window preferably with two, in-line sections in which each section is. slidable individually into a dummy shutter.

Afurther object of the present invention is to provide a window section having plastic, such as nylon guide rails or rollers, which slide over an inverted V-shaped track, that extends in .both the window opening and the dummy shutter. It should be apparent that both window sections may be slid into the dummy shutters permitting approximately 100%, ventilation through the window opening.

' .Another object of the present inventi on is the provision of a water-tight window construction and means for rapidly and easily removing the window section from the Window opening.

Another object of the present invention is the provision of a roller screen which may be attached under the overhang adjacent to the window opening.

A further object of the present invention is to provide a lockable sliding window unit which is reliably effective for the purposes intended.

The above and other features, objects and advantages of the present invention will be fully understood from the following description considered in connection with the accompanying illustrative drawings.

FIG. 1 is a front elevational view of a portion of a building containing a window frame and having a twosash slidable window and dummy shutters embodying my invention,

FIG. 2 is a sectional view of the window frame construction together with an additional slidable screen mounted in the front portion of the window frame,

FIG. 3 is a front elevational view of an alternative construction in which part of the shutter is broken away for purposes of clarity,

FIG. 3A is a sectional view taken along the lines 3A of FIG. 3,

FIG. 4 is a front elevational view of a stop for the two-sash slidable window,

FIG. 5 is an enlarged sectional view of the portion of the guide rails and track shown in the bottom left-hand side of FIG. 2 and FIG. 6 is a partial perspective view of the guide rails and track constructed in accordance with the teachings of my invention.

Referring more particularly to the drawings and especially to FIGS. 1, 2, 5 and 6 my sliding window and dummy shutter combination is illustrated in an outside wall 110 of a building preferably having an overhang 12 as shown in dotted lines in FIG. 1. Also as seen in dotted lines in FIG. 1, a roller screen 13 is ailixed under the overhang 12 adjacent to the window opening and may be unrolled and removably held at the bottom of the window opening to thereby screen the entire window opening. My improved window frame referred to generally by the numeral 8 comprises a sill member 14, a head member .16 and dummy shutter members 18. The shutter members 18 are preferably hinged at 20 to thereby give the appearance of actual shutters, but are not movable. As seen in FIG. 6, the shutter member 18 actually is hollowed out providing a large recess or opening 19 for the amazes retraction therein of either window section 22. It should be apparent therefore, that window sections 22 slide laterally into and out of the adjacent dummy shutter members when it is desired to open and close the same. Referring now more particularly to FIGS. 2, 5 and 6 it will be noted that the sill member 14 is sloped a few degrees downwardly in order to assist in the run-off of water from the window frame. Mounted on the sill member 14 is an. inverted V-shaped track 26 preferably constructed of aluminum and extending along the sill member 14 and thence into the bottom of the opening 19 of both shutter members 18. The window sections 22 are provided with a border 28 having a groove 30 extending along the bottom thereof. Groove 30 has an elongated insert 32 provided with elongated, spaced nylon rails 34. {Between the nylon rails 34 is a reentrant portion 36 in insert 32 that is made by means of a tool (not shown) which when forced therein swages the nylon rails 34 into an extremely tight fit in the insert 32 thereby preventing the rails 34 from falling out or loosening in the insert 32. It will be noted that the nylon rails 34 are bevelled at their ends 38 and 40 (FIG. 5) in order to complement the sloping sides of the inverted V-shaped track 26 and thereby prevent moisture seepage therethrough. Ob viously, wear on the nylon rails 34 will not remove the tight seal between the nylon rails 34 and the track 26 but will, on the contrary, only serve to even further seal the window section in the window frame. A screen .31 mounted in a frame 33 is disclosed in FIG. 2 positioned in front of the window section 22. The screen 3i may be easily removed when the same is not required.

The upper window guide track comprises a U-shaped section '42 having a projection 44 extending towards the interior thereof. A guide rail 46 rests on the top end of each window section 22 has a groove 48 in the side of guide rail 46 which is larger in the vertical dimension than the corresponding projection 44 of U-shaped section 42. An undulated spring 50 is captured between the U-shaped section 42 and the top of guide rail 46.

As shown in FIGS. 3 and 4, a stop element 52 is secured to head member 16 of my novel window frame.

The stop element 52 is provided with an elongated slot 54 I in which a screw 52. is tightened, the latter having its head portion on the interior of the window frame. Thus, if it is required to remove either window section 22 from the window frame 8 it is only necessary to loosen screw 56 and slide the stop element 52 upwardly and thereafter tightening the screw 56 to hold the stop element in its new, elevated position. Then, the window section 22 may be moved to the opening of the window frame and the former lifted upwardly against the pressure of spring 50 until the projection 44 of the U-shaped section 42 on the upper window guide track abuts the bottom of groove 48 of the guide rail 46. When this is accomplished, the nylon rails 34 are removed from contact with the V- shaped track 26 and spaced therefrom so that the window section 22 may be removed inwardly into the building. Since the U-shaped section 42 has a longer leg 54 on the outside of the building it should be apparent that it is not possible to remove the window section 22 in an outwardly direction.

An alternative construction embodying my invention is disclosed in FIGS. 3 and 3A. in this connection, the window enclosure 28 is provided with sheave-like rollers 58 which are adapted to roll over V-shaped track 26. The rollers 56 are mounted on an axle do in an insert 32, the latter being urged by means of spring 62 to cause the rollers 50 to securely engage track 26. The window section shown in FIGS. 3 and 3A may be removed from the window frame 8 in the same manner as the construction shown in FIGS. 2, 5 and 6.

While I have shown and described the preferred cm- Patented Oct. 10, 1961 bodiment of my invention, it will be understood that the latter may be embodied otherwise than as herein specifically illustrated or described and that in the illustrated embodiment certain changes in the details of construction and in the arrangement of parts may be made without departing from the underlying idea or principle of the invention within the scope of the appended claims.
